It's all a compromise these days.

The over-porting is something I've thought about as well. (he actually quoted me when he brought up this point
)
But the reviews don't seem to indicate that it has shitty low end. But maybe the response is covering for that a bit? This is not helping me... Just give me a damn torque curve. Or a test drive.
Over-porting is liveable if that means we un-cork the breathing, cam it, and bump up the rev limit, so long as fueling can support it and the rods/bearings can handle the extra rpm.
